Ported from heavy-duty/box#137 (heavy-duty/box#136) so the three repos'
reconcilers stay byte-identical. The state machine here was byte-identical to
box's before this change and remains so after -- only the scope:* taxonomy
differs, correctly.
decide_state() derived state from three inputs -- draft flag, requested
reviewers, submitted reviews -- and read NOTHING about mergeability or checks.
With the `if requested "$HUMAN"` short-circuit at the top of its precedence,
the label was sticky: once the maintainer was requested, a PR read
state:needs-human through conflicts, through red CI, through a force-push that
staled every approval.
In this repo the SECOND half is the live one: three PRs sit at
state:needs-human simultaneously with nothing saying which to merge first, and
they will conflict through CHANGELOG.md the moment one lands. The stickiness
has not bitten here yet only because nothing has conflicted -- the code carried
it identically, so the first merge would have reproduced box's situation.
The rule the label now keeps: state:needs-human means a human could merge this
RIGHT NOW, so anything making that false outranks the request that put it
there.
CONFLICTING or failing checks -> state:needs-rebase (new; the agent's to fix)
approvals staled by a push -> state:addressing (nobody reviewed this tree)
An UNFINISHED round still yields to an explicit human request -- MISSING
(nobody has reviewed yet) is a different fact from STALE (everyone reviewed
something else). UNKNOWN mergeability is NOT treated as unmergeable: GitHub
reports it for about a minute after every merge, and flapping every open PR
through needs-rebase on each merge would be worse than the bug. A failed read
degrades to the same "do not know" value.
Also adds merge-next -- the label this repo needs most today, since a correct
needs-human still does not say which of three ready PRs to merge first. Queue
order is intent, so the reconciler never sets it, only CLEARS it.
Fixtures 19 -> 29. DRY_RUN against this repo changes NOTHING, which is the
correct result: every open PR here is currently mergeable, so the new
precedence is a no-op on a healthy board and fires only when something is
actually wrong. npm test 623 passed.
Closes#127

codex's late #85/#98 round-3 finding, valid post-merge: the needs-human
auto-request fired only when the human had NEVER reviewed, so any earlier
human comment or stale approval left a fully-approved PR labeled
needs-human with nobody actually requested — a wedged handoff.
human_request_needed() now asks whether a fresh head-current human review
is missing (live request or head-current approval → nothing to ask;
anything else → request). Five new fixtures cover the wedge, the stale
approval, the satisfied handoff, and request suppression (19 total).

Maintainer direction: body-parsing agreement was a guess, and the machine
must not guess. COMMENTED is now unconditionally a non-verdict; the judgment
that a comment-only reviewer's round passed belongs to the PR AUTHOR, who
escalates by requesting the human's review — an explicit request is a fact,
and it is the machine's top-precedence input. Auto-request survives only for
the no-judgment case: three formal head-current approvals. CONTRIBUTING and
LABELS.md state the handoff; fixtures updated (14 transitions, including
author-escalation and the three-formal-approvals path).

Round-1 blockers, all three reviewers concurring:
- COMMENTED agreement now counts: agreement_signal recognizes the live bots'
durable markers (Verdict: Approve / I agree with everything / leading ✅) —
the gate to needs-human can actually close. Formal verdicts remain the
contract (CONTRIBUTING), this is the documented transitional workaround.
- Every counting verdict is bound to the head SHA; a stale approval parks the
PR in addressing (agent owes re-request) instead of promoting unreviewed
code. CHANGES_REQUESTED blocks at any head, per GitHub's own semantic.
- reconcile serializes under ONE job-level concurrency group; scope stays
per-PR. No more cron-vs-event race on the request-the-human-once guard.
- Sweep resilience: per-PR subshell (one failure logs and continues), label
edits warn instead of wedging; the self-heal claim now matches reality
(dispatch-only bootstrap).
- The state machine is extracted pure (globals in, state out) and sourceable:
test/labels-reconcile.sh proves 14 fixture transitions — comment-only
agreement, stale approval, comment-without-verdict, human precedence and
human-block — wired into CI.
